自己滚应该不会太难。
创建一个具有标准进度条属性的用户控件
Value
Maximum
Minimum
您可以创建一个派生属性,该属性使用 a 公式计算条形的大小:
ProgressBarWidth = (Value / (Maximum + Minimum) * ControlWidth) - Padding
更新值、最大值或最小值时会发生变化
将此绑定到进度条控件模板中的“栏”的宽度 - 这样,当 Value 属性更新时,进度条将调整大小。
你的酒吧看起来如何取决于你,但我想你只是想要一堆花哨的填充/渐变/发光效果 - 你可以在 Blend 中添加这些
免责声明:公式可能不正确!
如果您想尝试自己动手,这是我刚刚敲过的一个,它似乎可以正常工作
public partial class MyProgressBar : UserControl
{
public MyProgressBar()
{
InitializeComponent();
Loaded += new RoutedEventHandler(MyProgressBar_Loaded);
}
void MyProgressBar_Loaded(object sender, RoutedEventArgs e)
{
Update();
}
private static readonly DependencyProperty MaximumProperty = DependencyProperty.Register("Maximum", typeof(double), typeof(MyProgressBar), new PropertyMetadata(100d, OnMaximumChanged));
public double Maximum
{
get { return (double)GetValue(MaximumProperty); }
set { SetValue(MaximumProperty, value); }
}
private static readonly DependencyProperty MinimumProperty = DependencyProperty.Register("Minimum", typeof(double), typeof(MyProgressBar), new PropertyMetadata(0d, OnMinimumChanged));
public double Minimum
{
get { return (double)GetValue(MinimumProperty); }
set { SetValue(MinimumProperty, value); }
}
private static readonly DependencyProperty ValueProperty = DependencyProperty.Register("Value", typeof(double), typeof(MyProgressBar), new PropertyMetadata(50d, OnValueChanged));
public double Value
{
get { return (double)GetValue(ValueProperty); }
set { SetValue(ValueProperty, value); }
}
private static readonly DependencyProperty ProgressBarWidthProperty = DependencyProperty.Register("ProgressBarWidth", typeof(double), typeof(MyProgressBar), null);
private double ProgressBarWidth
{
get { return (double)GetValue(ProgressBarWidthProperty); }
set { SetValue(ProgressBarWidthProperty, value); }
}
static void OnValueChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
(o as MyProgressBar).Update();
}
static void OnMinimumChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
(o as MyProgressBar).Update();
}
static void OnMaximumChanged(DependencyObject o, DependencyPropertyChangedEventArgs e)
{
(o as MyProgressBar).Update();
}
void Update()
{
// The -2 is for the borders - there are probably better ways of doing this since you
// may want your template to have variable bits like border width etc which you'd use
// TemplateBinding for
ProgressBarWidth = Math.Min((Value / (Maximum + Minimum) * this.ActualWidth) - 2, this.ActualWidth - 2);
}
}

结果:
就像我说的那样,这样的事情很容易,但仍然考虑重新定义模板或使用原始模板,因为它确实支持正确操作系统上的发光
这是在我添加了一个“百分比”依赖属性并绑定到控件模板中之后:
更新代码Percent
是
Percentage = Math.Min((int)(Value / (Maximum + Minimum) * 100), 100);
编辑2:
我弄乱了填充并添加了一个白色的内边框,使它看起来更有光泽。唯一缺少的是闪亮的动画
顶部是我的控件,底部是默认的 WPF 之一
请记住,所有这些都可以通过编辑进度条控件模板来实现
这是更新的 XAML:
